 July 25, 2010, 12:04 User Defined function for scalar gradient caculation with Star ccm+ V4 #1 New Member   NVilius Join Date: Jul 2010 Posts: 3 Rep Power: 15 Hi all! I m modeling flow and heat transfer in a heat exchanger model. After convergence of a simulation (or even during the simulation), i would like to caculate the temperature gradient at any point of the computational domain. I have tried to have a look at the User guide for the implementation of user Fortran code into Star CCM+ but the examples found concern only very simple user profile codes. Could anyone help me please? Coolio Last edited by coolio; July 26, 2010 at 03:16.

If you are just interested in the magnitude value of the gradient vector just use "mag(grad(\$temperature))". lisa_china likes this. Last edited by willimanili; December 22, 2011 at 02:09. Reason: changed abs to mag
